Washington’s National Air and Space Museum was shut down yesterday afternoon and at least one protester was pepper-sprayed as about 200 — some with links to Occupy Wall Street — tried to bull their way past security guards.

No serious injuries were reported, and museum officials said they planned to reopen today.

The protesters, barred from entering, tried to storm in at about 3 p.m.

Some were members of Occupy DC, an offshoot of the 4-week-old Occupy Wall Street protest, The Washington Post reported.
